Steven Sasson is a pretty unassuming guy. But he changed the world. In this "video portrait" by David Friedman, Sasson briefly walks us through the birth of the digital camera, and muses about its implications since then.

It's strange—digital cameras, being cheap and pocketable, aren't a remarkable thing anymore. But to hear the voice of the man who created the thing, without whom the idea might have arrived much later, is like hearing it for the first time. An inventor's words aren't like anyone else's—probably because they come from a brain that saw a world without the digital camera and thought Hey, I'm going to change this.[David Friedman via Laughing Squid]
